Latest Patents
One of his latest patents is titled "Analog tracking circuit to improve dynamic and static image rejection of a frequency converter." This invention provides systems, devices, and methods related to frequency converter arrangements. The frequency converter arrangement converts a first signal centered at a first frequency to a second signal centered at a different frequency. It includes local oscillator (LO) circuitry and in-phase, quadrature-phase (IQ) mixer circuitry. The LO circuitry features duty cycle correction circuitry to adjust the duty cycle of input clock signals, along with coarse tuning circuitry responsive to a digital calibration code and analog tuning loop circuitry. Additionally, the LO circuitry incorporates quadrature divider circuitry that generates in-phase and quadrature-phase LO signals.
Another significant patent by Mostafa is focused on "Flicker noise elimination in a double balanced mixer DC bias circuit." This invention discloses a transmitter that reduces third-order harmonic (HD3) and intermodulation distortion (IMD3) for a gm stage of a mixer while minimizing flicker noise. The transmitter includes a balanced mixer, a transconductance stage connected to the mixer, and a bias circuit. The bias circuit features a programmable current source to provide a reference current and a replica circuit to replicate a DC signal of the transconductance stage.
